"Indiana, like many other states, has been targeted with a denial of service interruption," said Indiana Office of Technology spokesman Graig Lubsen. "The website was not hacked. A denial of service attack consists of sending many traffic requests at the same time in order to overwhelm a website and have it not be able to load. The denial of service interruption began at approximately 2:00, but the site has not been continuously down."

He said the site faced "intermittent outages" but never a full shutdown.
